Cisco 100Gbase Sr4 Qsfp Module Mpo Mtp Multimode Transceiver For High Density Data Centers

Experience scalable, high-performance connectivity in dense data-center environments with the Cisco QSFP Module for 100GBASE-SR4. This hot-swappable, quad-lane transceiver is purpose-built for optical networks and modern data centers, delivering four parallel 25 Gbps lanes over multimode fiber. Engineered for reliability and interoperability, it seamlessly integrates with Cisco switches, routers, and fabric interconnects to enable ultra-dense 100 Gigabit Ethernet deployments. Ideal for campus backbones, leaf-spine fabrics, and blade-server architectures, this module helps you expand your 100G capacity while keeping power usage and rack-footprint in check. Built to Cisco standards, it ensures predictable performance, robust thermal characteristics, and compatibility with established fiber infrastructure and patch panels.

• Unmatched 100GBASE-SR4 performance: Four parallel 25 Gbps lanes deliver up to 100 Gbps aggregate bandwidth over short-reach multimode fiber, enabling high-throughput interconnects in data centers, high-density racks, and storage networks.
• MPO/MTP multi-fiber connectivity: Optimized for OM3/OM4 multimode fiber with standard MPO/MTP cabling, simplifying deployments in new builds and existing fiber plants while preserving compatibility with widely used fiber infrastructure.
• Hot-swappable and field-proven reliability: The QSFP form factor is designed for live-network maintenance. Install or replace modules without powering down critical equipment, reducing downtime and improving operational agility.
• High-density, energy-efficient design: The compact QSFP+ package supports dense port layouts in top-of-rack and spine-leaf architectures, balancing performance with power efficiency to manage cooling and operating costs in modern data centers.
• Seamless Cisco ecosystem integration: Optimized for Cisco switches, routers, and fabric interconnects, featuring straightforward configuration and monitoring through standard Cisco management interfaces for plug-and-play interoperability.

Technical Details of Cisco QSFP Module

• Form Factor: QSFP+ (Quad Small Form-factor Pluggable)
• Data Rate: 100 Gbps (100GBASE-SR4)
• Interface/Connector: MPO/MTP multi-fiber connector for parallel optics
• Fiber Type: Multi-mode fiber (OM3/OM4)
• Compatibility: Engineered for Cisco flagship switches, routers, and fabric interconnects with standard management interfaces

How to install Cisco QSFP Module

• Prepare the environment: Follow standard ESD precautions and ensure you are working in a clean, static-safe area. Confirm your Cisco device supports QSFP+ 100GBASE-SR4 modules and the MPO/MTP fiber is properly rated for OM3/OM4.
• Identify the correct slot: Locate an available QSFP+ slot in your Cisco switch, router, or fabric interconnect. Verify that the slot is suitable for hot-swappable operation on your device model.
• Remove the protective shutter: If your platform uses a protective cover or shutter, remove it to expose the module receptacle. Do not touch the gold contacts.
• Insert the module: Align the QSFP+ module with the slot and gently push until it seats firmly. The latch will engage automatically or require a light click to lock, depending on the model.
• Connect the fiber: Attach the MPO/MTP armored or standard fiber harness to the module’s connector, ensuring a clean, straight alignment. Avoid bending fibers beyond recommended radii to prevent signal loss.
• Verify alignment and link: Power up (if applicable) and monitor the device management interface for module detection, link status, and indicated speed. Run basic connectivity tests to confirm that all four lanes are active and reporting error-free operation.
• Document and monitor: Record the module serial and port details in your network inventory. Use Cisco management tools to monitor link health, temperature, and utilization for proactive maintenance.
